The racket holds still: both player run cycles re-rolled steady-handed

Oliver, after the facing fix: still flashing, female worst. Film-strip
diagnosis in the pane: with facing pinned the racket STILL alternated —
frame 4 of the female cycle tucked it across the body, and half the frames
of both player cycles lost or shrank the hoop to cut fragments (overlapping
figures sliced by the even-spaced valley cuts).

Both cycles re-rolled with three new prompt rules that now live in
_runroll.py: the racket stays right of the midline in EVERY figure (named
again for the airborne pose, where it kept vanishing), and the figures
never overlap (no more sliced hoops — a debris-stripping pass was tried
and removed: after the recrop a real racket is indistinguishable from a
fragment, prevention beats cleanup). The model returns 2-row grids at
times; a coherent band is cropped and cut. Installed: racket-side spread
+0.01..+0.05 across all frames of both cycles (was a full side swap).
